Homebrew PCBs

Hi Stefan,

Your patient guidance helped me to create a PCB using a tone transfer 
method. Look in the files section: 
http://groups.yahoo.com/group/Homebrew_PCBs/files/Tone%
20Transfer_mikez/

Since my latest post I was able to successfully iron the image and 
etch it. Yes, there are few small problems like shorts and missing 
tracks but overall comparing to what I had until today it is a 99.99 
success rate.

What helped me is your advice that pressure is not significant and 
that you had more success with low pressure. So did I. In fact, I can 
attribut my shorts to high pressure (before I understood what you 
really meant). 

The dark smear is from imprper washing of laser print with acetone: I 
rubed it into the board.

Stefan, I am thrilled with that method. I was able to do the board 
from printo dry PCB under one hour and not ruching. Next time I can 
probably do it under 30 minutes. Thank you for all your help!!!

Mike
